We have been told many times that speed cameras cause accidents

Why did cars ever have rev counters. I never look at mine and have no
idea what an appropriate rev reading is.

When I learnt to drive reasonably priced cars didn't have rev counters
and so I was taught to listen to the pitch of the engine. I think
listening is better than a rev counter as we instinctively hear whereas
we need to pro-actively read a rev counter.

There are rev counters on a couple of the cars available to me. I never
even look at them while driving. Driving on the ordinary road network
should never necessitate running the engine at in-the-red speeds and
just listening to the engine note should be more than enough.
